Inspection of micro-LEDs for Next-Generation Displays

Hamamatsu Photonics has developed a system for high-speed inspection of micro-LEDs on wafers to detect abnormalities in their external appearance, intensity and wavelength of their light emissions. This inspection system utilizes a photoluminescence (PL) measurement technique* that is based on our advanced image processing technology and a newly developed imaging module with our unique optical design technology.

The MiNYTM PL makes fast pass/fail decisions when inspecting micro-LEDs, which will contribute to an increased product yield for use in display applications and will also help to increase the R&D efficiency of micro-LEDs. Furthermore, the MiNYTM PL will also streamline the 100 percent inspection process of micro-LEDs in future mass production lines.

Sales of the MiNYTM PL has started on Monday March 8, 2021 to LED and display manufacturers in domestic and overseas markets.

*PL measurement technique is a versatile method for evaluating characteristics of LED and other devices by capturing and analyzing light-excited photoluminescence images in a non-contact and non-invasive manner.
